Specification of Letters Patent. Patented Fel 25, 1913.

Application filed December 28, 1909. Serial No. 535,267.

To all whom it may concern:

Be it known that I, WALTER E. COFFIN, of Cleveland, Guyahoga county,Ohio, have in- .vented a new and useful Timber-Pocket, of

tional views showing other forms of my in- .vention applied to car sillswhere they abut a ainst the end sills of the car framing; F1 s. 9 and 10are detail views showing the adjustable key of Fig. 8; Fig. 11 is a viewsimilar to Fig. 1 showing still another form of the invention; Fig. 12is a perspective view of a modified form of the key; Figs.

' 13 and 14 are front elevations partly in section showing the key ofFigs. 11 and 12, the key being shown in different positlons in thepocket; and Fig. 15 is a view similar to Fig.

8 showing" another form of pocket; Fig. 16

is a front elevation of the pocket shown in Figrlfi; Fig. 17 is a viewsnnilar to Fig. 15 but showing still another form of pocket;

. Fig.18 is a section on the line XVIII-XVIII of F ig. 17; and Fig. 19is a perspective View showing another form of key.

as for use in fastening the timbers of railway My invention has relationto metal pockets cars together, and commonly known as timbei pockets. Anobject of my invention 1s to provide a 'device ofthis character, inwhich the open side of the pocket may be closed by a bolt or key memberwhich can be inserted or removed from the side without in any way1nte'rferin with the timber bolts used for securing e timbers together.

A further object of my inventlon which is inherent in the preferredforms thereof, is to provide'a timber pocket having means wherebyshrinkage in the timbers can be readilytaken up. Other objects andadvantages of my invention will hereinafter appear.

Referring first to that form of my nvention, which is shown in Fig. 1,the timber pocket consists of a casting co prising a flat base plate 2,projecting side walls 3and .top portion 4, the bottom portion of theopen.-

pocket between the side flanges 3 bein 5 deslgnates a key which isadapte to-be inserted in a ertures in the lower portions of the sideanges 3 in the manner shown for the purpose of closing the open side ofthe pocket after the timber 6 has been inserted therein. This timber isshouldered or tenoned at 7 to enter the pocket, and is also preferablycutaway at 8 to receive the key 5. The keyis shown as formed with a head9 at one end, and is secured by means of a pin or cotter 10. This keycan be readily inserted and removed from the side after the timber hasbeen put in place and without in any way disturbing the usual timberbolts. The base plate may be provided with one or more bosses orprojections 11, which enter holes cut therefor in the timber 11. Ifdesired, the usual lugs or bosses can be omitted and simple screw holesprovided.

The modification shown inFigs. 3, 4 and 5 illustrate differentarrangements of these bosses. Fig. 3 shows a pocket having two circularbosses Fig. 4 shows a pocket having four circular bosses; Fig. 5 showsone having bosses or projections of angular form.

The timber pocket shown in Fig. '7 is similar to that'first described,except that the apertures 12 in the side flanges for the key 13 areelongated vertically. By drawing up on the timber bolts 14, the keycanmove vertically in the slot 12 a short distanceto compensate forshrinkage in the timbers.

sists of a member 15 of angular form in cross-section, and which isformed withga bolt-hole 16 which is located eccentrically of both thevertical and transverse center lines of the member. This key is insertedinto the pocket from the bottom, and a bolt 17 which may be secured byan ordinary nut 18 is passed through the key as shown. The member 15 canbeturned to seat on any one of its four sides, and owing to theeccentric location. of the bolt hole, gives a different position for thebolt in each of its different positions, thus providing for taking upshrinkage of the timbers. It will'bfe obvious that instead of beingarranged-to give four differentadjustments, a key may be employed whichwill gave two, three, orv more than four adjustments.

In the construction shown in Fig. 11 a I key member 19 is employed ofthe form shown in detail in Fig. 12, and which has a dowel portion orprojection 20 adapted for 1 or other timber, as the case may be, arenotassumed entirely by the key, but are taken insertion in one of thehollow bosses or proj ections 2-1 on the base portion of the pocket.

By reason of the provision of this dowel portion, downward strains uponthe carhne partially by the bearing of the dowel por tion in the boss orsocket.

in Fig. '11,; and is secured against displacement by a pin orcotter 23.The dowel pro:

ject ion. is eccentric. with respect to thehorizontal axis of the keymember, so that the key may bereversed to give different-- adjustments.

In Figs. 13' and 1451 also; shows. key

her like that shown in Figs. 11 and 12-. The

pin 22 is bent at one endto form-ahead 24.

and is secured attheotherendby a cotter 23. These two figures alsoillustrate the reversible character of the key" shownin Fig 12.

, In the form shown in Figs.- 15 and 16 the open side of the pocket isclosed by a. re-

movable piece or plate' 27, which-is securedin place by vertical bolts28 having nuts-29 4 at their lower ends. With this form,shr ink age istaken up by simply tightening the nuts. This form .of pocket is alsoshownas provided with screw holes'30 in its base.

The form shown in F igs. 17 and 18 is' one which can be used toadvantage where it is desired to remove the timber sidewise in stead ofby lowering it.- Such a case would occur in the removal of side sills incar construction. In, this case the end of the timher is cut awaysufficiently to engage the top and bottom walls of the pocket, and alsothe central dowel or pro'ection 31, the

pocket being open. at the si e. After the timber has been inserted bysliding it from the side, the transverse bolts 82 are put in position,with washers 33, which' give a broad bearing upon the timber, the boltsbeing drawn up tightly by means of the nuts 34:.

Fig. 19 shows a split key. 35,, which can be used in place of the keysshown in the other figures. With this form of key, after it has beenputin place the ends can be bent outwardly, thus securing the key inplace without the use of an additional cotter.

.A flat -bo1t or pin 22 is passed through the key as shown Theadvantages of my invention will be apparent from the foregoingdescription, since it provides a timber pocket which can be readilyapplied, which greatly facilitates i the connection with the parts, andwhich,

in the preferred forms, also provides simple and ready means for takingup 't1mber shrinkages.

It will be obvious that my invention is 1. -,A' timber pocket havingscribed.

not limited to't'he' use of the particular forms of keys for securingmeans, which I have herein shown and described, since devices of variousother forms may be employed. s
